Problem using TabControl with WebBrowser control

HI,

In one of my VB.NET form, I have a tabcontrol where one tabpage will include a WebBrowser control to display some web contents.

However, when I run my program, I found that the tabcontrol is minimized to very very small...........and I need to put

Me.tcPolicy.Location = New System.Drawing.Point(0, 56)
Me.tcPolicy.Size = New System.Drawing.Size(764, 408)

in the form_Activated event to resize it again!

Is it a bug? Any managed web browser control available yet?

Thx!
